  • nounA straightforward loanword for testing in the technical sense, such as software testing or product testing. It is less common than native alternatives, so it tends to appear in specialized or industry contexts rather than everyday speech.
  • 試し
    nounListed as testing, experiment, test, or examination, but on its own it is a less common way to say 'testing' and is really the 'trial' or 'attempt' element seen in set expressions. Seldom the word you want for ordinary testing.

For careful scrutiny or selection use 吟味; for technical software or product testing 「テスティング」 works; 試 covers tests and experiments but is a marginal, less common choice for 'testing'.
